The FCC Starts Its Wireless Microphone Investigation. Will Broadcasters Throw Broadway Under A Bus?

The FCC has just released a Notice of Proposed Rulemaking addressing the problem of wireless microphone operations in the 700 MHz Band and how it may screw up the introduction of new public safety and commercial wireless services. It basically proposes to adopt the recommendations we made to prohibit any future manufacture, sale or importation of wireless microphones that operate on the relevant 700 MHz frequencies, and prohibit operation on those bands after the DTV transition in February.

Along the way, the Commission asks for comment on our informal complaint and Petition for Rulemaking. Oh yes, and the NPRM also announced that the Enforcement Bureau has commenced an investigation into the wireless microphone manufacturers and their sales tactics.

I wish I could take all the credit for this one, but I really gotta hand it to Shure. I’m not saying that Shure’s insistence on dragging FCC engineers out to field testing so they could see first hand the blatant way in which Shure and others violate FCC rules, getting all their illegal customers to right into the FCC by the thousands and regale the FCC with tales of unauthorized use all over the country, and generally rubbing the FCC’s nose in the fact that Shure and the rest of the industry were engaged in widescale violation of the rules over and over and OVER again necessarily had anything to do with this. I will merely note that it is a happy coincidence of timing that the FCC commenced its investigation the Friday following the field testing, and immediately thereafter put our Petition out for comment attached to an item already in the works. No, it is no doubt my good looks and charm once again bending the FCC to my will.

To the extent the industry press has picked up on this, it has (surprise!) assigned credit for this to the great Google Overlords. Mind you, the same article also thinks that wireless microphones “produced little or no complaints because their signals have traditionally been programmed to avoid TV channels,” so this will tell you something about the accuracy of their analysis. (For those wondering, wireless microphones are dumb devices and the user selects the channel. It has no sensing equipment or database or any of the interference avoidance tech proposed for white space devices.)

I would also say that much as I would love to see this as a sign that the FCC supports opening up the white spaces for unlicensed use, I don’t. The NPRM is very carefully neutral on the subject, without any statements from Commissioners one way or another, and voted on circulation (meaning it is non-controversial). No, I think the Register pretty much got it right when they described this as “having sold off 700MHz to the highest bidders last year, the FCC now has a responsibility to clear the area before the new tenants move in.” The ball on white spaces, whether licensed, unlicensed, or not used at all is still very much up in the air.

Mind you, this certainly impacts the debate over the white spaces, and potentially removes a stumbling block by providing a road map on how to address the wireless microphone issue in a way that punishes spectrum scofflaws like Shure while protecting users like churches deceived by Shure’s sales tactics (and give parties an incentive to come to the table and do a deal over real interference concerns before the FCC bites their patooties off). And I think it is fair to say that we did help move the debate forward by providing the FCC with the pathway to making this possible. But I would say that all the Commissioners are still waiting for the field testing results to come in before making a final decision on the merits.

What is really critical here for the white spaces proceeding is that the broadcasters now have to make a very unpleasant choice. Do they embrace the radio pirates and forgive Shure for unleashing a million illegal transmitters all over “their” spectrum? Or do they stick to their usual guns and condemn any unauthorized use of the broadcast bands as unmitigated evil and warn that sanctioning a million new authorized users — with new General Wireless Microphone Users added every day — could utterly destroy broadcast television as we know it? Either way presents problems for broadcasters — with the added bonus of highlighting their blatant hypocrisy. Embracing the likes of Shure and unauthorized users undercuts all the hysteria broadcasters have so carefully cultivated, especially when they have always maintained that opening this spectrum to anyone new would destroy free over the air television. OTOH, siding with the FCC on enforcement against Shure and warning the FCC not to allow millions of transmitters operating at higher power and with fewer protections in the white spaces destroys their ability to use Broadway, the Grand Ole Opry, and all those megachurches as human shields.

Needless to say, the broadcasters have desperately sought to avoid saying anything on the subject and have tried to spin this to their advantage: “Gosh, moving wireless microphones off Channels 52-69 will sure make it harder to fit in all them white spaces devices,” claims David Donovan of the Association for Maximum Service Television, a trade association for TV broadcasters that has fought against any sharing of the white spaces.

The problem with this statement is that, according to the FCC, there are only 156 licensed wireless microphones authorized to operate on Channels 52-69. That’s not a heck of a lot of crowding. Unless, of course, MSTV plans to support our Petition for Rulemaking and support creation of a General Wireless Microphone Service licensed by rule and open to the general public.

Mind you I expect that MSTV, like the McCain campaign, will continue to get a free ride on this from an obsequious broadcast trade press and a tech press that cannot get past the Great Google Overlords. But they are going to have to file comments on this at some point. And I imagine that, as they come in to lobby against white spaces, the good folks at the Commission will want their opinion on this separate but related matter. I’ll certainly be interested in rading those Ex Partes.

Stay tuned . . .

    Too bad that folks like Shure don’t look at this whole affair as an opportuntiy to sell new microphones. Shure can blame the FCC as they rake in the cash and the FCC can avoid the lawsuit to come if the space isn’t vacated. Sounds like a win-win to me.

    It does: They are essentially correct.

    “(For those wondering, wireless microphones are dumb devices and the user selects the channel. It has no sensing equipment or database or any of the interference avoidance tech proposed for white space devices.)”
    And for those of you who’d like to know how wireless mics are actually used in the field . . . The first thing done by a professional user is to pull out a scanner or spectrum analyzer and search for clear spectrum. Even the amateur will generally turn on his wireless mic *receiver* first to scan through for a clear frequency *before* any transmitter is turned on. Only after clear frequencies are determined, will a transmitter be turned on.

    “OTOH, siding with the FCC on enforcement against Shure and warning the FCC not to allow millions of transmitters operating at higher power and with fewer protections in the white spaces destroys their ability to use Broadway . . .”
    Kindly define “higher power” please (in dBm, dBW, or watts).

    Henry what is the beef with Shure? There are many other manufacturers who were campaigning againts the FCC ruling just like Shure. I also wouldn’t say that Shure is using anyone as a Shield, I’ve seen complaints directly from Broadway and Major Churches(Rick Warren of Saddleback.) This ruling could also be detrimental to broadcaster themselves, for example mobile news crews that use wireless mics.
